Be it-known that 'L'HENRY SCHULHOEE, a subject of the Emperor ofAustria-Hungary, residing at New York, in the county and State 0f NewYork, have invented new and useful Improvements in Roofing, of which thefollowing is a specification.- 1

My invention relatesv to improvements in metallic roofing; and itconsists, essentially, in a tile provided with an upwardly-project ingtongue on one side, a groove corresponding to the tongue on the oppositeside, and an upwardly-projecting tongue on one end, all of whichis morefully pointed out in the following specification and claims andillustrated in the accompanying drawings, in which- Figure l representsa plan view of a portion of a roof constructed according to myinvention.. Fig. 2 is a vertical section thereof in 'the plane x x, Fig.l. Fig. 3 is a vertieal-seotion in the plane' yy, Fig. l. Fig. 4 is aplan view of a tile. Fig. 5 is a longitudinal section thereof in theplane x' x', Fig. 4. Fig. 6 is a transverse section in the plane y y',Fig. 4.

Similar letters indicate corresponding parts.

ln the drawings, referring at present to Figs. 4, 5, and 6,'the letterAdesignates a tile, which is provided with an upwardly-projectingtongue, a, on one side, a groove, b, on the opposite side, and with adownwardly-proj ecting tongue, c, on one end. The opposite end has aportion, d,.which projects beyond the ends of the tongue a and-groove b,and which may be curved, as shown, or provided with any other ornamentaloutline.

In applying these tiles A to a roof (see Figs. 1, 2, and 3) a smallcrevice is left between the roof-boards B, Fig. 2, into which 'isinserted the end tongue, c, of the ti1e,whe'reby it is prevented frommoving vertically. The lower portion, d, of the tile next above,whichportion projects beyond the ends of thetongue a and groove b, `overlapsthe upper end of the tile below, thereby preventing leakage at thistongues and grooves are formed by bending f The tilesare preferablymadeof metal, andthe the metal in a manner well'kn-own to those skilledin the art. n
